Prior to version 2.9.9, a security issue in the Nuclei project affected users utilizing Nuclei as Go code (SDK) running custom templates. This issue did not affect CLI users. The problem was related to sanitization issues with payload loading in sandbox mode. There was a potential risk with payloads loading in sandbox mode. The issue occurred due to relative paths not being converted to absolute paths before doing the check for `sandbox` flag allowing arbitrary files to be read on the filesystem in certain cases when using Nuclei from `Go` SDK implementation. \n\nThis issue has been fixed in version 2.9.9. The maintainers have also enabled sandbox by default for filesystem loading. This can be optionally disabled if required. The `-sandbox` option has been deprecated and is now divided into two new options: `-lfa` (allow local file access) which is enabled by default and `-lna` (restrict local network access) which can be enabled by users optionally. The `-lfa` allows file (payload) access anywhere on the system (disabling sandbox effectively), and `-lna` blocks connections to the local/private network."}, {"lang": "es", "value": "\"Nuclei es un esc\u00e1ner de vulnerabilidades. Antes de la versi\u00f3n 2.9.9, un problema de seguridad en el proyecto Nuclei afectaba a los usuarios que utilizaban Nuclei como c\u00f3digo Go (SDK) ejecutando plantillas personalizadas. Este problema no afectaba a los usuarios de CLI. El problema estaba relacionado con problemas de sanitizaci\u00f3n con la carga de payload en modo sandbox. Exist\u00eda un riesgo potencial con la carga de payloads en modo sandbox. El problema se deb\u00eda a que las rutas relativas no se convert\u00edan en rutas absolutas antes de realizar la comprobaci\u00f3n del indicador `sandbox`, lo que permit\u00eda la lectura de archivos arbitrarios en el sistema de archivos en determinados casos cuando se utilizaba la implementaci\u00f3n del SDK Nuclei from `Go`. \n\nEste problema se ha solucionado en la versi\u00f3n 2.9.9. Los mantenedores tambi\u00e9n han habilitado sandbox por defecto para la carga del sistema de archivos. Esto se puede desactivar opcionalmente si es necesario. La opci\u00f3n `-sandbox` ha quedado obsoleta y ahora se divide en dos nuevas opciones: `-lfa` (permitir el acceso local a ficheros) que est\u00e1 activada por defecto y `-lna` (restringir el acceso local a la red) que puede ser activada por los usuarios opcionalmente. El `-lfa` permite el acceso a archivos (payload) en cualquier parte del sistema (deshabilitando efectivamente el sandbox), y `-lna` bloquea las conexiones a la red local/privada.\""}], "lastModified": "2023-08-10T14:08:02.640", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:projectdiscovery:nuclei:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "645B1A56-6CB4-40CC-B443-38CB78CA657B", "versionEndExcluding": "2.9.9"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
